Warning: Full spoilers follow for Dark Phoenix.
Fox's mutant movie universe may be coming to a close as Marvel Studios takes control of the X-Men characters, but not before debuting one last fan-favorite character. Dazzler finally makes her big screen debut in Dark Phoenix, albeit only in cameo form and apparently played by Halston Sage (The Orville). She has no dialogue but is seen singing -- and using her mutant powers to generate a light show while wearing her trademark white outfit -- during the X-Men's party on the grounds of the mansion.
We'll never see this version of Dazzler become a full-fledged member of the X-Men since the Fox series is coming to an end, but her appearance is still a fun nod to fans of the comics. And if you're not up on all things Dazzler, here's a brief primer on the character.
